[0031] Through the implementation of the above technical solution, the movable table 16 is first driven upward by the driving mechanism, and the die-casting upper mold 17 is driven upward and separated from the die-casting lower mold 4 under the push of multiple columns 5, and then the top plate 8 is pulled upward to separate the top plate 8 from the three positioning shafts 6, and the top plate 8 is rotated around the fourth higher positioning shaft 6 to expose the die cavity of the die-casting lower mold 4, and then the die-casting material is put into the die cavity of the die-casting lower mold 4, and the top plate 8 is rotated after being put in place, and the top plate 8 is sleeved on the multiple positioning shafts 6, and then the rotating lock buckle 7 is rotated to lock the rotating lock buckle 7 into the lock groove 10 so that the positioning shaft 6 and the top plate 8 are in a locked state, and then the die-casting upper mold 17 is driven downward by the driving mechanism to cooperate with the die-casting lower mold 4 to die-cast the die-casting material. The rubber seal molding device is convenient for opening the upper mold and moving the upper mold to one side to discharge and unload the rubber seal die-casting molding process.

[0032] In this embodiment, in order to further provide a rotary lock catch 7, the rotary lock catch 7 includes a cylinder 12 provided with a top cover, an inner cavity 21 is provided in the cylinder 12, a rotating shaft 20 is provided on the top cover along the axial direction, a locking tongue 11 is fixedly sleeved on the rotating shaft 20, an arc hole 14 is provided on the side of the cylinder 12 to provide the locking tongue 11 with rotation, and a handle 13 is fixedly connected to the upper end of the rotating shaft 20. The operation mode of the rotary lock catch 7 is: the rotating shaft 20 is driven to rotate by rotating the handle 13, and then the locking tongue 11 is driven to rotate, and the two states of inserting into the lock slot 10 and leaving the lock slot 10 are realized by the rotation of the locking tongue 11. The height of the arc hole 14, the height of the lock slot 10 and the thickness of the locking tongue 11 are all the same, so as to better lock the vertical position. The opening position of the lock slot 10 can be provided with a rounded chamfer, and the side of the locking tongue 11 facing the lock slot 10 can also be provided with a rounded chamfer, so as to better cooperate with the insertion.
